Im not fluent in it either lol, i admit.... I use a hex calculator to do the work for me,
And i also use win hex (i think its called, its on my other laptop i use for ecu work)
Win hex will help translate hex into binary,

I use it mainly these days for converting vw dashes into audi spec, and at first it took me forwever to work out lol.
Your getting it tho mate,
